Diaphragm, Vagus Nerve and Stress: What Your Breathing May Be Telling You

Most people think of breathing as something automatic. You breathe in, breathe out, and rarely pay attention to what is happening inside the body. But your breathing pattern can influence much more than your lungs.

The diaphragm is the large breathing muscle under the ribs. The vagus nerve is a major nerve that travels from the brain through the chest and abdomen. These systems are connected with breathing, digestion, heart rate, relaxation, and the body’s stress response.
